MULTIPLE PAGE AND rom'rnn commune-non FOR GAU'GING WEIGHING MACHINES.

INSTRUMENTS AND Application filedseptember 20, 1928.. Serial No.307,166;

This invention relates generally to the class of indicating devices, andhas particular reference to improved dial'and' pointer constructionconstituting an element of one of a variety of gauging instruments,weighing machines, etc. I

-Up to the present time, gauging instruments are provided with dialfaces and pointers which necessitate their reading by observation of thesame from one direction only. Obviously, this in many instances, causesno littie inconvenience, in addition to a loss of time, in making areading therefrom. I h 1 To overcome the above mentioned disadvantagesand objections, the present invention comprehends an indicator which isprovided with a plurality of dial faces and pointers whereby the samemay be read from practically'any direction in which it is viewed, thusmaterially increa ciency thereof; a

The invention further contemplates a multiple face and pointerconstruction for ganging instruments which is not undulycomplicated,which is inexpensive to produce and; which is highly efficient in itspurpose.

lVith the above recited and other objects inv View, reference is had tothe following description and accompanying drawings, in which there isexhibited one example or embodiment of the invention, while the claimsdefine the actual. scope of the same.

In the drawings 1. o Figure 1 is a side View of a gauging instrumentincluding, a dial and pointer construction in accordance withthejinvention.

Figure 2 a vertical sectional View therethrough taken approximately onthe line indicated at 22 in Figure 3.

Figure 3 is an enlarged horizontal sectional view taken approximately011 the linev indicated at 33 in Figure 2.

Figure at is a detail perspective view of one of the dial face platesdisassembled.

Referring to the drawings by characters of reference, thev indicatorconstituting the present invention includes a tubularcasing 5 oftransparentmaterial whichis suitably attached or connectedlwith the bodyG'of the gauging instrument, which instrument may be of any type or foranypurpose. A plurality of similarly constructed dial face plates 7 areattached to the inner surface of the. tubular casing 5 in spacedrelation to the instrument.

Whatis claimed is:

transparentcasing,aplurality, of dial faces .11

each other and projecting inwardly therc from to define between theadjacent blades, slots 8' which extend longitudinally ofthe casing 5.The outer surfaces of the dial face plates are provided with suitablegradu ations 9 and indicia 10 relative thereto. v slide 11 is mountedfor longitudinal or axial movement within the casing and ,isdisposedbehind the dial'faces. The slide is provided with aplurality of pointers12 correspond' .ing in numbertothe numberof dial plates 7, whichpointers extend through the slots Sand areprovided with angularlydisposed terminals '13 designed to move over the graduations 9 Anysuitable means may be employed for operatively connecting the slide withthe actuating element or elements of the gauging instrument, but asillustrated, said means consists'of an endless flexible sprocket chain14 which is trained around the sprocket wheels 15, and 16, it beingunder-,

to A stood thatone leaf of the sprocket chain is v secured or attachedtothe slide 11 for effect- 'ing longitudinal movement of the slide inopposite directions in accordance with the movement of the sprocketchain. In practice, the slide is preferably mounted on a guide 17, suchas 'a bar or rod; If desired, the guide rod or bar 17 may also serve inthe capacity of a support for one or both of the sprocket wheels '15 and16, and in addition, 1

said guide rod or bar may serve the purpose of anchoring the casing 5 tothe body 6 of the instrumentby attaching a cap 19 to one end of said rodor. bar, the opposite end of which is anchored or securedto" the body ofIn use and operation, it is apparent that with the multiplicity ofdialfaces and pointers, circumferen'tially or otherwise ar-.

rangedto face in a plurality of directi0ns,1 that readings may be takenirrespective of the radial idirectlon of the eye of the observer withrespectsto the indicator.

1. In a gauging, instrument, a tubular transparent casing, a pluralityof dial faces projecting inwardly therefrom, a slide dis-; posed withinthe casing. and behind the dial faces for longitudinal .movement and apointer for each 1 dial face connected to the slide for movementtherewith.

2;In agauging instrument, a tubular F projecting inwardly therefrom, a Islide disposed within the casing and behind the dial faces forlongitudinal movement, a pointer for each dial lace connected to the slile for movement therewith and an operative connection between a movingpart oi the gauging instrument and the slide for eliecting longitudinalmovement thereof.

3. In a gauging instrument, a tubular transpz-u'ent casing, projectinginwardly therefrom, posed within the casing and behind the dial facesfor longitudinal movement, a pointer for each dial. face connected tothe slide for movement therewith and a longitudinally extending guideupon whicn the slide mounted for longitudinal movement.

4. In a gauging instrui'nent, a tubular transparent casing, a plui lityoi dial faces projecting inwardly thereirom, a slide (lir-sposed Withinthe casing and behind the dial faces for longitudinal movement, apointer for each dial face connected to theslide for movement therewith,a longitudinally ere tending guide upon which the slide is mounted forlongitudinal movement and means operatively connected with the slide aplurality of dial laces slide die.

and with a moving part olthe gauging instrument for effectinglongitudinal movement of the slide on its guide. 7

5. In a gauging instrument, a tubular transparent casing, a plurality ofdial faces projecting inwardly there'lroima slide disposed within thecasing and behind the dial faces for longitudinal movement, a pointerfor each dial face connected to the slide for lIlO'VQlIlGIli; therewith,a longitudinally extending guide upon which the slide is mounted forlongitudinal movement and means operatively connected with the slide andwith a moving part of the gauging instrument for effecting longitudinal,movement of the slide on its guide,'said means consisting of an endlessflexible element. guide members around which same is trained to disposeone lead of said flexible element within the casing and a connectionbetween said lead and the slide.
